i COOLING DEVICE.`

Application filed February 2G, 1924. Serial No. 695,142.

To all whom t may concern:

Be it known that I, Gus'r T. HAGLUND, a citizen of the United States,residing at Spokane, in Spokane County and State of- VVashington, haveinvented certain new and useful Improvements in .Cooling Devices, of'

which the following is a specification.

My present invention relates to improvements in cooling devices of therefrigerator type for domestic use wherein a cabinet is utilized and astream of water is caused to flow through casings therein for thepurpose of transferring heat from the interior of the cabinet to theflowing fluid, thus reducing the temperature of the interior of thecabinet. The device of my invention is adapted for usey in connectionwith water supply of a house or residence and is interposed in the watersupply system in 'order that water for domestic uses will pass throughthe cooler and thus provide an additionaluse without extra expense orincreased consumption of As is well known the water contained in thest-reet mains is usually at a much lower degree of temperature than thatcontained in the house-pipes, and also lower than the atmospherictemperature of the house. from the street main and passes through thecooler, the interior of the cooler is refrigerated for the purpose ofpreserving foods and provisions in the cooler. My invention consists incertain novel combinations and arrangements of parts in the cooler aswill hereinafter be more fully set forth and claimed.

In the accompanying drawings I have illustrated one complete example ofthe physical embodiment of my invention wherein the parts are combinedand arranged in accord ance with the best mode I have thus far devisedfor the practical application of the principles of my invention.

Figure 1 is a digrammatic view showing one installation of the cooler ofmy invention in connection with the water system of a house or dwelling.Y

Figure 2 is a detail perspective view'of one of the plurality of casingsused in the interior of the cooler cabinet.

Figure 3 is a transverse vertical sectional View at line 3-3 of Figure2.'

Figure 4 is a horizontal sectional view at line 4-4 of Figure 3.

While I have herein referred to the cooler Therefore when the water isdrawn as adapted for domestic use, it will be apparent that theinvention isapplicable for use in other relations, where a flow of waterunder pressure is available for the purpose.

In order that the general relation of parts may readily he understood Ihave indicated in Figure v1 the'main water supply pipe 1 receiving waterat normal pressure from the street main for supplying the water sys temof the house. A trap 2 and usual control valves 3 and 4 are interposedin the main pipe and the supply pipe 5 for the house rises from the mainpipe and passing'r through the cooler indicated as a whole by thenumeral6, the water flows through the outlet pipe 7 from the cooler to a faucetpipe 8 from which water may be drawn off for domestic purposes throughthe faucet 9. Another branch pipe 10 is indcated as connected with thelower pipe 11 andthis pipe has a valve 12 for connection therewith ofthe hose for sprinkling the lawn or other uses exterior yof the house.

In addition td these two specified uses the water supply is drawn offthrough other outlets from the water system in the house, and as all thewater of the house system passes through the cooler, it will be apparentthat the supply in the cooler is intermittently changed and relativelycool water passing through the cooler will withdraw' the heattherefrom..

The( interior of the cooler or cabinet 6 is provided with a plurality ofcasings, three of which are indicated as 13, 14, and 15. These casingsare of similar construction, cast as box-like structures from metal,with wide areas or surfaces for transmission of heat from the atmospherewithin the cabinet to the interior of the casing. The cas ings are flat,closed bodies and are spaced in the cabinet to form supporting shelvesIfor the food or provisions` or if desired sup` porting trays may beplaced on the casings for the contents of the cabinet.

The lower casing is supplied with water from the inlet pipe 5, and afterpassing upwardly through the casing 13 the water flows through verticalpipe 16 to the intermediate casing 14, thence through the verticalconnecting pipe 17 to the upper casing 15, and through pipe 7 to thewater system of the house. y

Each of the casings is fashioned with an inlet port 18 in its bottom andan outlet port 19 in its top wall for connection therewith or' the inletand outlet pipes of the casing.

The water is caused to flow upwardly through the series of casings, in atortuous passage, for more eect-ively withdrawing heat from the entireupper and lower walls of the casings, by the use of a. pair oflongitudinally extending, Vertical partitions 2O and 2l7 which formcommunicating chambers 22, 23, and 24 within the casing. Thelongitudinally extending vertical partitions connect the upper and lowerwalls ot the flat casings, but at one end each partition terminates nearan opposite end wall of the casing, thus affording communication betweenthe compartments as indicated by the arrows in Figure et, and as seen bydotted lines in Figure 2.

In the enlarged sectional View of Figure 3 it will be seen that thebottom ot' the inlet chamber or compartment 22 is at a lower level thanthe bottom of the intermediate chamber 23, and the bottom of the latterchamber is at a lower level than the bottom of the outlet chamber 24.This variation in the levels of the bottoms of compartments or chambersis carried out in all of the casings, and the entire bottom area in theinterior of the casing gradually declines from the outlet compartment tothe inlet compartment. Thus the water under pressure is caused to flowupwardly through the interior of the cabinet for cooling orrefrigerating purposes. It it is desired to drain the cooler, it may becut oil if desired from the water pipes of the house by closing asuitably located valve, then the valve 3 is closed, and valve 4tremaining open will permit water to be discharged through the trap 2.Under these conditions the water in the cabinet will readily drain overt-he declining bottoms of the plurality of casings to `the pipe 5 foremptying the cooler.

while I have illustrated three casings, it will be understood that thesecasings are interchangeable, and that a larger or smaller number may beutilized to increase or diminish the capacity of the cooler. The cooleror cabinet of course encloses the casings, and the cabinet may beinsulated in suitable manner against the transmission of heat throughits walls. The size of the casings may be varied, and deviations may bemade from the preferred rectangular shape as shown, if desired orrequired, and it will also be apparent that the number of partitionswithin the casings may be varied, without departing from the spirit ofmy invention as set forth in the following claim.

Having thus fully set forth my invention, what I claim as new and desireto secure by Letters Patent is- The combination with an enclosingcabinet, of a series of superposed spaced casings having connecting'pipes, an inlet and an outlet pipe, means within each of said casings'forming communicating compartments and a. tortuous passage and thebottom levels of said compartments desclining toward the inlet pipe.

In testimony whereof I aiiX my signature.
